Frequently asked questions
- Is the XC3S400A-4FG320I still in production?
- No. The XC3S400A-4FG320I has been discontinued by the manufacturer. Discontinued parts can still be quoted — send a request with the quantity and any date-code requirements.
- Is there a direct replacement for the XC3S400A-4FG320I?
- No. The manufacturer's discontinuation notice states there is no direct replacement for the XC3S400A-4FG320I. Either the remaining supply is used, or the board is revised around a current device.
- What package is the XC3S400A-4FG320I?
- The XC3S400A-4FG320I comes in the FG320 package (320-FBGA, 19 × 19 mm).
- Which versions of the XC3S400A come in industrial temperature?
- The XC3S400A-4FG320I is itself an industrial-temperature part (-40 °C to 100 °C, junction). 5 other XC3S400A parts are industrial temperature. A different speed grade or package is not a drop-in replacement, so check it against your design.XC3S400A-4FG400IXC3S400A-4FGG320IXC3S400A-4FGG400IXC3S400A-4FT256IXC3S400A-4FTG256I
